Apparently I am supposed to be arguing for perks AND attributes, but won't admit it. Not true. This is a personal thing, my opinion nothing more, but I have never been happy with attributes in games. In the original dungeons and dragons, you rolled your stats, and they didn't change in normal play, you were stuck with them, you didn't get stronger, or wiser, and that was that, your character.
In TES, all the attributes were changeable, you could level up whichever you wanted, only the amount per level changing.
Not happy with either. Why? It makes sense that you can become stronger by fighting, that your personality could increase slightly by becoming practiced at persuading people, but how the hell do you become more intelligent at all, let alone starting off as a muscle bound Nord warrior, then eventually having an intelligence of 100, the same maximum as an Altmer mage?
If there was an attribute system that had racial minimum/maximums, limited ability to increase ( how does a Breton end up with three and a bit times more endurance than they started with? ), and some such as intelligence and luck unable to be improved at all, then I would whole-heartedly agree with attributes, but as it is I would rather stick with skills, perks, and health/stamina/magicka increases.
You can learn to cast spells more efficiently, and learn to harness more magical energy, but you won't become more intelligent, unless you define intelligence as only being more proficient with magic, hey presto!, increased magicka is the same thing.
And before someone calls me out for saying 'you don't want endurance to increase, but health is ok', in the original Dand D it said something to the effect of hit points being a mixture of stamina, health, combat experience, the ability to dodge, and just not being quite so in the way of that axe swing anymore. You can't become three times as tough, you can become three times better at surviving.
Sorry about the rant, but I don't like being told what I am thinking.
